Product Description:

The MDD090A-N-020-N2M-110PR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for positioning axes and feed drives on automated machinery. The motor belongs to the 090 frame class and uses the standard housing and balancing arrangement for this product line. This layout supports uniform mechanical behavior across machines that use the same motor platform.

The motor has a centering diameter of 110 mm, which allows accurate location in flange-mounted assemblies. Under continuous stall conditions, it delivers 3.7 Nm of torque, and normal operation is based on a nominal speed of 2000 rpm. Feedback is handled through digital servo feedback (DSF), and the integrated multiturn absolute encoder tracks shaft position over multiple revolutions without external batteries. Power and signal connections exit on the right side, which can simplify cable routing when several axes are installed close together. The standard A-length stack keeps the housing compact, and the key shaft follows a DIN form that suits common industrial couplings.

For static load holding or emergency stops, the installed blocking brake provides 11.0 Nm of torque. Electrical connection is made through a keyed connector, which mates with preassembled hybrid cables used in compatible drive systems. The output shaft has a keyway, and a fitted shaft seal helps keep lubricant from migrating toward the bearing area. The motor uses a single-ended shaft, so side B is omitted to reduce overhang when the unit is mounted to gearheads or belt pulleys. This arrangement keeps the drive end compact and supports installations where space around the coupling is limited.
